Hi Folk,

 

I have requirement and still i didn't find the correct logic to get this implemented.

Scenario: I have 5 check boxes as below:

1. Laptop

2. Mobile

3. Desktop

4. Printer

5. Mouse

 

currently user can select all check boxes at a time but i want to let user select only check boxes as per below combination,

 

1. Mobile

2. Mobile & laptop

3. Mobile & desktop

4. Mouse

5. Mouse &Mobile

6. Printer

7. Printer , Mobile & Desktop

 

user should not be able to select all combination of check boxes.

 

Thanks in advance for any help.

Hi @Vijay Baokar,

 

Please see a reply I made to a post just a few days ago solving to a pretty much similar requirement. The only difference would be restrict this to 1 rather than 3.

Kudos to @Hitoshi Ozawa who has provided a solution to this exact question previously.

 

Check the below link:

For future usage and in case of broken links, here's the script courtesy of: @Hitoshi Ozawa

function onSubmit() {
    //Set the mandatory checkbox variable names and total mandatory count here
    var mandatoryVars = 'checkbox1,checkbox2,checkbox3,checkbox4,checkbox5,checkbox6,checkbox7,checkbox8,checkbox9,checkbox10,checkbox11,checkbox12,checkbox13,checkbox14,checkbox15,checkbox16';
    var mandatoryCount = 1; //You can chqange this value to whatever required
    var maxCount = 1; //You can chqange this value to whatever required

    var passed = forceMandatoryCheckboxes(mandatoryVars, mandatoryCount);
    if (!passed) {
        //Abort the submit
        alert('Please select ' + '1.'); //You can chqange this value to whatever required
        return false;
    }

    function forceMandatoryCheckboxes(mandatory, count) {
        mandatory = mandatory.split(',');
        var cnt = 0;
        for (var i = 0; i < mandatory.length; i++) {
            if (g_form.getValue(mandatory[i]) == 'true') {
                cnt++;
                if (cnt > count) {
                    return false;
                }
            }
        }
        return (cnt == count);
    }
}
